The subjective organization of input and output events in memory

In order to study the organization of memory for self-performed actions, 80 participants were presented with 20 action phrases for ten consecutive study-test cycles. Enactment was manipulated both in the input phase and in the output phase by having participants say or enact the phrases during encoding and/or during testing. Enactment at input or output generally enhanced both the quantity and the accuracy of recall and also improved output monitoring. More important, subjective organization, as indexed by the tendency to recall the same two phrases successively across repeated recall tests, was significant for all conditions, even on the first pair of trials, and increased systematically with repeated study-test cycles. Enactment neither impaired nor enhanced the amount of organization, and in all conditions a positive correlation was obtained between recall and subjective organization. Some commonalities in the nature of memory organization were found across all conditions. The results suggest that enactment may lead to more differentiated memory traces, resulting in more accurate recall. Although subjective organization was clearly observed when enactment was involved, its contribution to the enhancement of recall deserves further examination.

Individual differences in habituation: Some methodological and conceptual issues

The personality correlates of habituation were investigated. A moderate intensity tone was presented 20 times on each of three sessions, and skin conductance and heart rate were recorded. There were no relationships between individual differences in rate of habituation and any of the personality dimensions assessed (which included, among others, manifest anxiety and introversion-extraversion). Some possible reasons are discussed for this lack of results, as well as for conflicting findings which fill the literature. Specifically, various methods of measuring habituation are examined and their interrelationships described. None of the measures derived showed adequate consistency either across sessions or over response modalities.     

Emotion Regulation Strategies in Cognitive Behavioral Therapy for Panic Disorder

Emotion regulation (ER) has been incorporated into many models of psychopathology, but it has not been examined directly in cognitive behavioral therapy (CBT) for panic disorder with agoraphobia (PD/A). In this study, a preliminary model of ER in CBT for PD/A is proposed based on existing theories, and several propositions of the model are tested. We hypothesized that increases in cognitive reappraisal would precede decreases in biased cognitions, decreases in expressive suppression would follow decreases in biased cognitions, and a reduction in symptom severity would follow decreases in expressive suppression. Twenty-nine patients who received CBT for PD/A completed weekly self-report measures of symptom severity, anxiety sensitivity, reappraisal and expressive suppression. In addition, patients were compared to a matched normal sample. Cross-lagged analyses partially supported the hypotheses. Reappraisal did not change until late stages of therapy and was generally not associated with treatment outcome. Suppression decreased significantly and exhibited a reciprocal relationship with biased cognitions. Symptom reduction followed decreases in suppression as hypothesized. However, patients did not differ in ER from matched controls at either pre- or posttreatment. Results suggest the important distinction between reappraisal and appraisal, and stress the role of session-by-session decreases in suppression as a predictor of symptom reduction.     

Response latency as a predictor of the accuracy of children's reports

Researchers have explored various diagnostic cues to the accuracy of information provided by child eyewitnesses. Previous studies indicated that children's confidence in their reports predicts the relative accuracy of these reports, and that the confidence-accuracy relationship generally improves as children grow older. In this study, we examined the added contribution of response latency to the prediction of children's accuracy over and above that of confidence ratings. In Experiments 1 and 2, 2nd and 5th graders studied picture-event pairs and were tested using forced-choice, 2-alternative, or 5-alternative questions. In Experiment 3, children watched a slideshow depicting a story and were tested by 5-alternative questions about story details. The children indicated their confidence in each response, and response latency was measured. The results of all experiments suggested that children in both age groups relied on response latency as a cue for confidence, and this reliance contributed to the success with which they monitored the accuracy of their reports. When the test format was easy (Experiment 1), 2nd graders were as accurate as 5th graders in monitoring the accuracy of their answers, and the latency of their responses was no less predictive of accuracy. When the task was more difficult, age differences emerged. Nevertheless, in all experiments and for both age groups, response latency was found to have added value for predicting accuracy over and above that of confidence. Theoretical and practical implications of these findings for predicting the accuracy of children's reports are discussed.     

Easy comes,easy goes? The link between learning and remembering and its exploitation in metacognition

The cue-utilization view in metacognition assumes that judgments of learning (JOLs) are based on inferences from mnemonic cues deriving from the online processing of items during learning. This view calls for a specification of the underlying heuristics, their validity in predicting memory performance, and the extent to which they are utilized. This study examines one such heuristic: easily learned, easily remembered (ELER). We first show that ease of learning, as indexed by self-paced study time and by the number of trials to acquisition, is indeed a valid cue for recall success. We then demonstrate that this correlation between learning and rememberingunderlies metacognitive predictions about the future recallability of different items. The results are discussed in terms of the idea that metacognitive judgments incorporate knowledge about the internal ecology of cognitive processes, much as the perception of the external world embodies knowledge about the ecological structure of the environment.     

Adolescents' participation in organized activities and developmental success 2 and 8 years after high school: do sponsorship, duration, and intensity matter?

Using data from the National Education Longitudinal Study, the authors examined relations between educational, civic, and occupational success in young adulthood and the duration and intensity of participation in organized activities during high school. They also examined these relations as a function of sponsorship (i.e., school- vs. community-sponsored organized activities). They found that youths who participated in organized activities for 2 years demonstrated more favorable educational and civic outcomes in young adulthood than those who participated for 1 year. More intensive participation was also associated with greater educational, civic, and occupational success in young adulthood--particularly among youths who participated in activities for 2 years. Educational attainment often mediated the relations between temporal measures of participation and young adult civic and occupational outcomes. With the exception of analyses examining occupational success, findings varied little as a function of sponsorship. Of note, analyses revealed that both temporal measures of participation were positively associated with young adult outcomes as many as 8 years after high school.
